BBC Weather: Carol Kirkwood warns Brits ‘it’s going to be cold’
After a mostly settled January with high pressure and sunny skies, this week sees a change in pressure bringing snow and rain over coastal regions, with colder temperatures and winds across much of the country. Maps and charts show that from Wednesday, conditions begin to change for the worse, with a Scandinavian weather front affecting the west of Britain.
Maps from WXCharts hold Wednesday will begin with wet spells across much of Scotland and the north of England before pushing down into the Midlands and Wales.
Rainfall is expected to be light, at 1mm an hour, with wind gusts up to 50mph by 9am on Wednesday.
Temperatures for midweek are expected to be brisk with 1C across much of Britain by 6am, warming up to 6C by the evening.
However, as Wednesday comes to a close, a pressure system sees snow and rain begin to build to the west of Britain, with parts of the west coast like Norwich seeing rain by midnight.
The UK is set to be battered by western front of snow this week

Moving into Thursday and the weather system building on the west coast begins to push eastwards into the UK, bringing snow and freezing temperatures.
By 9am, 1cm of snow will fall an hour over Norwich and Hull, while the mercury reads at 0C for much of England and Wales.
In the north and parts of Scotland, Thursday morning could reach temperatures as cold as -3C, before climbing back to 0C by midday.
Due to the colder temperatures, fog and overnight frosts are likely for these areas.
WXCharts then sees conditions stabilise moving into the weekend, with snow remaining on the ground throughout the week.

Nick Finnis, Netweather.tv senior forecaster, wrote for the agency’s website that Thursday sees conditions turn “briefly colder” as “a northerly [weather system] develops”.
He said: “After a bright and chilly start across southern England, with some local fog patches, clouding over from the northwest with a little patchy rain around lunchtime, before clearing south to sunnier conditions already across the north, as the wind turns northwesterly.
“Most areas dry and sunny in the afternoon but with a cold wind, with the colder air digging in across the north wintry showers will push south across northern Scotland and later NE England. Temperatures reaching 5-8C in the north, 7-10C in the south.
“A cold start with a widespread frost on Thursday leading into a cold day, with a keen northerly wind towards the east, which will feed in wintry showers for a time along eastern coasts.
“Most places will be dry and sunny though, with high pressure close to the west. Temperatures reaching 4-5C at best in the east, 6-8C in the west.”
Nick Finnis said ‘A cold start with a widespread frost on Thursday leading into a cold day’
For the weekend, Mr Finnis noted high pressure will begin to build again for Britain, meaning sunny days.
He added: “High pressure builds east across the UK on Friday, so for most it will be dry and less cold, best of the sunshine across England and Wales, cloudier for Scotland and N. Ireland with the flow off the Atlantic.”
Jim Dale, a senior meteorologist at British Weather Services, also told Express.co.uk: “As we get towards the end of the month – the coldest on average parts of the year – what we’re seeing is the high pressure pulling away south and west, allowing a north-easterly air stream to come in.
“That may well start to bring some snow events towards the latter stages of the month – so that last week of January. I’m talking now about January 25-28.”
The Met Office issued a yellow weather warning for fog across the south coast
It comes as the Met Office issued a yellow weather warning for fog across the south coast.
The warning is in effect from 5pm on Tuesday to 6am on Wednesday, and reads: “Fog has been persistent in places through Tuesday and is expected to thicken up here during Tuesday evening as well as form in other areas.
“The fog will likely be dense with visibility of less than 100 m at times. The fog will persist for many overnight before clearing from the northwest early Wednesday morning.”
Speaking about the warning, Met Office forecaster Craig Snell said: “The fog is going to be most widespread in southern, eastern England, into the Midlands and the east side of Wales too.
“Not everywhere within that warning will be foggy, but the main message to drivers is to allow some extra time for your journey because there could be fog around.
“It could have a knock-on effect on public transport, so there could be delays to bus journeys and train journeys. The fog will tend to clear as the morning goes on.
“It may linger on in a few spots, but towards lunchtime conditions should be much better.”
